Proton Decay and Axion Dark Matter in SO(10) Grand Unification via Minimal Left-Right Symmetry

Yuta Hamada, Masahiro Ibe, Yu Muramatsu +2

We study the proton lifetime in the $SO(10)$ Grand Unified Theory (GUT), which has the left-right (LR) symmetric gauge theory below the GUT scale. In particular, we focus on the mi…
